Abstract: This research initiative explores the value of performance recording in the multiplier flock of multi-tiered sheep breeding schemes integrating commercial and breeding structures. Discounted gene flow theory was used to model the flow of genes from the selected multiplier rams that are mated to commercial ewes. A model which predicts genetic trends and gene flows at an individual trait level was combined with trait economic values to aggregate the total industry benefits associated with alternate recording and selection strategies. While recording efforts and molecular technology adds significant costs to the breeding schemes, their application in multiplier flocks also adds considerable margins by increasing accuracy of selection with consequent higher rates of progress.
